How do you prove something is true? For mathematicians, the answer is simple: Start with some basic assumptions and proceed, step by step, to the conclusion. QED, proof complete. If there’s a mistake anywhere, an […]
In recent years, quantum physicists and engineers have made significant strides toward the development of highly performing quantum computing systems. Realizing a quantum advantage over classical computing systems and enabling the stable operation of quantum […]
Insider Brief U.S. Senators Maggie Hassan and Marsha Blackburn are pressing the Pentagon for answers on its quantum sensing efforts, citing concerns over China’s advances in the field, as reported by Defense One. Quantum sensing, […]
Insider Brief IonQ has demonstrated remote ion-ion entanglement, a key milestone towards quantum networking and scaling its quantum systems. The IonQ team successfully connected two trapped ion qubits from separate trap wells using entangled photons, […]
Quantum 8, 1493 (2024). https://doi.org/10.22331/q-2024-10-04-1493 The computational capabilities of near-term quantum computers are limited by the noisy execution of gate operations and a limited number of physical qubits. Hybrid variational algorithms are well-suited to near-term […]
Quantum 8, 1492 (2024). https://doi.org/10.22331/q-2024-10-04-1492 We prove that the stabilizer fidelity is multiplicative for the tensor product of an arbitrary number of single-qubit states. We also show that the relative entropy of magic becomes additive […]
Quantum 8, 1491 (2024). https://doi.org/10.22331/q-2024-10-04-1491 ZX-calculus has proved to be a useful tool for quantum technology with a wide range of successful applications. Most of these applications are of an algebraic nature. However, other tasks […]
Researchers adopt a new ligand to enhance the efficiency and stability of perovskite quantum dot solar cells. Solar cell efficiency increases to 15.3% by correcting distortions on the surface of quantum dots. Click to rate […]
Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power efficiency but has yet to be realized due […]
Physicists have succeeded in coupling two Andreev qubits coherently over a macroscopic distance for the first time. They achieved this with the help of microwave photons generated in a narrow superconducting resonator. The results lay […]
